SAFETY CHECK PRIOR TO OPERATION

WARNING: Be sure the machine is unplugged and the power switch turned OFF when inspecting the machine.

1.Check to be sure all parts and fasteners are properly attached and tight.

2.Be sure the blade is properly installed and adjusted.

3.Check the operation of theTable Adjustment Handle (#150). One rotation of the handle will raise or lower the table by 2mm (0.0787”).

Plug in the machine to prepare to check the motor and blade function.

1.Turn ON the machine by moving the switch up.

Note: The safety switch cover must be in place for the switch to operate.

2.Do not insert any work materials into the planer.Allow it to spin up to full speed. Determine if the machine is operating smoothly, not making any excessive noises or vibrations. If not, the machine is ready to operate.

WARNING: CHECK BLADE SETTINGAND TIGHTNESS BEFORE INITIAL USE.

OPERATION

WARNING: Be sure to wear ANSI-approved eye protection, and observe other safety precautions before starting this machine.

1.Measure your workpiece to determine its current thickness, and the amount you desire to plane off. Remember the maximum depth of cut is 1/8”. If you need to remove more than this, you will make repeated cuts.

2.Set the cutting depth by turning the TableAdjustment Handle (#150) until the pointer indicates the correct depth on the scale.

3.Be sure the machine is OFF and the power cord unplugged. Insert the workpiece into the planer and

visually check your setting to assure that no more than 1/8” will be planed off the workpiece.

WARNING: Attempting to plane more than 1/8” at a time may cause the planer to jam; potentially causing the workpiece to splinter and be ejected from the machine, or the motor to jam and possibly burn out. Never attempt to plane more than 1/8” at a time.

4.When you are satisfied the cut is properly set up, remove the workpiece from the machine. Plug in the planer, and turn the power switch ON, by flipping it up. Allow the planer to spin up to full speed.

5.Position the workpiece on the extension roller and table so that it is level. If you are planing a long board, you may need support tables on both sides of

the planer to keep the workpiece level as its full length passes through the planer.

6.Feed the workpiece into the planer, no faster than the

stated feed rate (23 feet per minute). The planer should maintain its speed. If the planer slows down noticably, reduce the feed rate. If the planer still bogs down, remove the workpiece and adjust for a shallower cut.

WARNING: Do not allow your hands to move any closer to the planer than the rollers on the table extensions. Never allow your hands to enter the machine while it is turned ON. Severe injury can result.
